    (October university for modern sciences and Arts MSA, 2023) Elkattan, AbdelRahman; Elkholy, Janna; Magdy, Mohammed; Essam, Mostafa; Khaled, Mostafa; Fayed, Yousef
    This work is done to measure the sound density and improve its quality. And this is done by measuring the sound intensity in different situations and surroundings. To determine the effect of significant parameters throughout the sound measurement. The results of the various experiments of the sound measurement are viewed by applying some tools in Design of Experiments (DOF), Such as Taguchi method and Analysis of Variance (ANOVA) [1]. In these experiments there are four factors considered, they are temperature, distance, wind speed and angle of the sensor. These factors were chosen because they are the most parameters that can affect the quality of the sound. The results show that the factor speed is the most significant factor with percentage 1.79% according to the ANOVA table. Therefore, this work is considered as an effective tool to find the important parameters and their effect in sound measurement.

    Impact of inflation on stock market performance
    (October University of Modern Sciences and Arts, 2019) Maged, Rami; Abbas, Youssef; Mohsen, Aya; Essam, Mostafa; Hassan, Omar
    In the literature, it is known that there is a relationship between inflation rate and stock market performance. most studies proves that there is a negative relationship between the inflation and stock market performance, even with different methodologies the outcome proves the negative relationship, According to Upadhyay (2017) they used the consumer price index and the national stock exchange indicator and the result are sufficient to ensure that changes in stock prices over the period of selected time are not due to fluctuations in the CPI, but due to the changes in stock prices due to certain other factors available on the market. Stock market performance is measured with many indicators and one of them EGX30, and trade volume. This research aims to investigate whether if the inflation rate has a significant impact on stock market performance measured by EGX30, and trade volume. The data will be analyzed using statistical program called SPSS, the analysis will be done through descriptive analysis, correlation and multivariate regression analysis (MANOVA). The results were that there is a significant impact for the inflation rate on stock market performance.
